Other Parts Discussed in Thread: TPS40170-Q1

Hello,

If I want to use two TPS40170-Q1 as below, Do I only need to set M/S pin as one is Master & the other is Slave and connect Sync pins ?

Or Need more setting?

Regards,

Nicky

HI Nicky,

According to the datasheet, it seems that yes thats what you need the M/S mode pin selected as well as the SYNC pin to be connected. From your schematic i see that you can also control which TPS device that you want to enable first which is good.

Thanks
